I'm packaging my script into an EXE with pyinstaller, which works great! However, when I do this, I lose the ability to read parameters via CMD window. My code is structured like so: import argparse import sys class CLI(): def __init__(self, args:list, foo, bar): self.foo = foo self.bar = bar self.parser = argparse.ArgumentParser(description='parser') self.add_args() # Add arguments to self.parser self._args = self.parser.parse_args(args) # This line never runs or does nothing def add_args(self): self.parser.add_argument('-w', help='Hello World') if __name__ == "__main__": foo = 1 bar = 2 cli = CLI(args=sys.argv[1:], foo=foo, bar=bar) I also use the following script to package this code into an EXE with pyinstaller: pyinstaller --noconfirm --onefile --windowed "script.py" I can't tell for the life of me why it fails to execute parse_args when launching via EXE. Normal .py script works fine, and I've verified that the args variable is passed in successfully and contains the arguments I pass in.To pass in args, I'm using a CMD windows to execute a command such as script.py -h. I've seen some folks discussing this behavior in this thread, and I implemented the above based on some comments there. Unfortunately, it's still not working. Using the code above, I expect argparse to execute the same actions it performs when passing in arguments via script.exe -h as it does via python script.py -h. I'm not seeing anywhere that this configuration is explicitly unsupported, so any ideas? EDIT: Included minimum reproducible example and example pyinstaller script that reproduces this behavior.
